We look at the division of 44715903 by 393 
The aim is to understand the frequency of 393 in 44715903.

Advancing to step 1:
When dividing 4 by 393, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 393

Advancing to step 2:
393 can be fit into 44 0 times, resulting in a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 393

Let's proceed to step 3:
393 goes into 447 1 times with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 393 from 447 and we're left with 54.
Append the next digit (1) from the dividend to 54 and continue with: 541 / 393

Advancing to step 4:
393 can be fit into 541 1 times, resulting in a remainder of 148.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 393 from 541, we get 148.
Grab the next digit (5) from the dividend, add it to 148, then carry on: 1485 / 393

Let's proceed to step 5:
393 goes into 1485 3 times with a remainder of 306.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtract 1179 from 1485 to get 306.
Bring next digit (9) of the dividend behind the 306 and repeat the process: 3069 / 393

On to step 6:
393 goes into 3069 7 times with a remainder of 318.
The number 7 becomes the next digit in our result. 
Result so far: 1137.0
If we take 2751 away from 3069, we end up with 318.
Append the next digit (0) from the dividend to 318 and continue with: 3180 / 393

Advancing to step 7:
393 can be fit into 3180 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 11378.0
The remainder is 36 after subtracting 3144 from 3180.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 393

Going ahead to step 8:
393 can be fit into 363 0 times, resulting in a remainder of 363.
The next digit of our result is 0. 
Result so far: 113780.0
The remainder is 363 after subtracting 0 from 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Advancing to step 9:
If we divide 3630 by 393, we get 9 and a remainder of 93.
The next digit of our result is 9. 
Result so far: 113780.9
The remainder is 93 after subtracting 3537 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 10:
If we divide 930 by 393, we get 2 and a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 113780.92
Subtracting 786 from 930 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
1440 divided by 393 is 3 with a remainder of 261.
Record the quotient 3 as the next digit in the result. 
Result so far: 113780.923
Subtracting 1179 from 1440 leaves us with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Step 12:
When dividing 2610 by 393, we get 6 with a remainder of 252.
The next digit of our result is 6. 
Result so far: 113780.9236
If we take 2358 away from 2610, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 13:
When dividing 2520 by 393, we get 6 with a remainder of 162.
The number 6 becomes the next digit in our result. 
Result so far: 113780.92366
If we subtract 2358 from 2520, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final result is 113780.92366 with a remainder of 0.000162.
